Four Long Island men were among 11 frat boys charged in upstate Plattsburgh with killing a pledge during hazing rituals.

Among the men hit with a raft of charges – including criminally negligent homicide, five counts each of conspiracy, first-degree hazing and second-degree reckless endangerment – were Alex Fischer, 21, of Selden; Jeffery Meyer, 21, of Southold; John E. Bernius, 21, of Ronkonkoma; and Patrick J. Stasiukiewicz, 21, of Mattituck.

There were more than 150 individual charges lodged against the 11 last week, and the number could increase after a grand jury considers the case.

The students were part of Psi Epsilon Chi, a rogue fraternity whose recognition was withdrawn by Plattsburgh State University in 1998 because of alcohol violations.

Police charged the men with killing freshman Walter Dean Jennings by forcing him to drink huge amounts of water through a funnel.

The cause of death was listed as water intoxication, a condition where excessive water intake causes the brain to swell.

“Your mother always told you can’t drink enough water,” Plattsburgh Police Chief Desmond Racicot said. “But she never told you to take a large funnel and drink pitchers and pitchers of it, forcing you to do it until you throw up.”

Jennings had undergone a series of abuses over a 10-day period and died March 12, officials said.
